 DETAILED DESCRIPTION OF THE DRAWINGS

Referring to the figures, there is shown footwear 10 which may be readily modified by a user. Referring to FIG. 1, the footwear 10 is shown for the left foot; but it should be realized that the discussion and explanation below are equally applicable to footwear for the right foot. Footwear 10 includes 3 loops (or plugs) 11, 13 and 15 which extend from the underside of the footwear to the topside and which for ease of description will be referred to as vertical loops. The use of these vertical loops 11, 13 and 15 is known. These vertical loops are generally used in a known manner to enable straps to be attached and to hold the foot of the wearer. The footwear embodying the invention may include none or any number of vertical loops.

Footwear (also termed “sandals”) 10 embodying the invention defines over known footwear in that it includes horizontal retaining loops (21L, 23L, 25L, 21R, 23R, 25R and 27) extending along the sides of the footwear, as shown in the figures. The horizontal loops may also be referred to as “side straps” or “bands”. The loops formed in accordance with the invention are referred to as “horizontal” loops since they extend in a horizontal plane along the outer periphery or perimeter of the sole, in the embodiments shown in the accompanying figures, the horizontal retaining loops are formed by winding a string or cord or leather strip (e.g., 301, 302, 303) through tunnels (e.g., 41, 43, 45, 47) extending across the width of the sole of the footwear between the top layer 101 and the bottom layer 102 of the footwear. The use of string, cord or leather to make the loops has been indicated. However any other suitable flexible material or substance of sufficient strength and durability (e.g., plastic strips) can be used instead.

As shown in FIGS. 5 and 6, the horizontal loops enable a user to tie a variety of different ribbons to, through and around the horizontal loops to give the footwear different appearances and to more securely attach the footwear to the foot of the wearer.

Referring to FIGS. 2, 2A, 2B and 2C, there is shown a number of spaced apart tunnels 41, 43, 45 and 47 extending across the full width of the footwear 10. In FIGS. 2, 2A, and 2B the sole 100 (which is made to conform to the shape of a foot) is shown to be formed of a single relatively thick layer. The tunnels (which may also be referred to as grooves or vias) are formed through the center of the sole between the top surface 101 and the bottom surface 102 of the sole. Tunnel 41 has ends designated as A and B; Tunnel 43 has ends designated as C and D; Tunnel 45 has ends designated as E and F; and Tunnel 47 has ends designated as G and H.

FIG. 2A is a cross section of the footwear 10 taken across a tunnel region and is intended to illustrate that each tunnel, or via, is formed across the entire width of the footwear 10, between the right side (R) and the left side (L) of the footwear and generally midway (centrally) between the top (101) and bottom (102) surfaces of the footwear. FIG. 2B is a cross section of the footwear 10 taken along its length (from heel region to toe region) to illustrate that tunnels (41, 43, 45, 47) are formed, generally parallel to each other, in a spaced apart relationship along the length of the footwear, generally midway between the top (101) and bottom (102) layers or surfaces of the sole. FIG. 2C is a top view showing the spacing of the tunnels or grooves along the length of the sole. The showing of 4 tunnels is for purpose of illustration and there may be more or less than 4 tunnels. The tunnels may be formed by drilling the sole or punching or any other suitable manufacturing process. The thickness of the sole may vary over a wide range so long as the thickness is sufficient to enable the formation of tunnels which are wide enough to accommodate the strands of strings that pass or crisscross through the tunnels.

FIG. 20 is a cross sectional diagram intended to show that the sole 100 may be formed with two layers (201, 202) firmly attached (glued or cemented) to each other. In FIG. 2D the tunnels are shown to be formed in the upper layer. But they could be also formed between the two layers and even in the bottom layer depending on the relative thicknesses of the two layers.

FIG. 2E is a cross sectional diagram intended to show that the sole 100 may be formed with three layers (201, 202, 203) firmly attached (glued or cemented) to each other. In FIG. 2E the tunnels are shown to be formed in the middle layer 202. FIG. 2F is a three layered sole, like FIG. 2E, but is intended to show that the tunnels or grooves could be formed between the top surface of the middle layer 202 and the bottom surface of the top layer 203.

FIG. 2G shows that a heel loop 271 can be formed with an additional loop 272 attached to heel loop 271 to help secure the heel loop 271 to the heel or ankle of a user, as further describe below.

The structure shown in FIGS. 2, 2A, 2B 2C, 2D, 2E, 2F and 2G enables horizontal loops, straps or bands (21, 23, 25, and 27) to be formed along the sides of the sole. The loops may be formed or strung in many different ways as illustrated in FIGS. 3, 3A 3B and 4. A significant aspect of the invention is that the loops emerge from the side of the footwear and extend along the side of the sole of the footwear. This significant since the foot of a user can lie flat and comfortably along the total top surface of the footwear. That is, footwear embodying the invention require no bumps or uprights going vertically through the sole. However, it is possible to use vertical loops as mentioned above with footwear embodying the invention.

In FIG. 3 there is shown, by way of example, a string/strap 301 which is looped in a figure 8-like configuration beginning at the one end of tunnel 41 designated as A through tunnel 41 to the point designated as B at the end of tunnel 41. Then, the string 301 is wound (looking down at the drawing of FIG. 3) along the right side of the sole of the footwear to the one end of tunnel 43 designated as C and via tunnel 43 to the end of tunnel 43 designated as D. Then, the string 301 is strung along the left side of the sole of the footwear to the one end of tunnel 45 designated as E and via tunnel 45 to the end of tunnel 45 designated as F. Then, the string 301 is strung along the right side of the sole to the one end of tunnel 47 designated as G. The string 301 is then looped back through tunnel 47 to the other end of tunnel 47 designated as H and then along the left hand side of the sole to the end of tunnel 45 designated as E and then through tunnel 45 to the end of tunnel 45 designated as F. The string 301 is then run along the right side of the sole of the footwear to the end of tunnel 43 designated as C and through tunnel 43 to the end of tunnel 43 designated as D. The one end of string 301 (which is arbitrarily referred to as the front end) is then looped from point D along the left side of the footwear to point. A and tied to, or attached, to the other end of string 301 (which is arbitrarily referred to as the back end) to form a closed loop. The attachment may be completed by making a knot 311 or by use of any other attaching mechanism.

In FIG. 3, the portions of the string 301 extending between points: (a) A and form a horizontal loop 21L; (b) B and C form a horizontal loop 21R; (c) D and E form a horizontal loop 23L; (d) C and F form a horizontal loop 23R, (e) F and G form a horizontal loop 25R: and (f) E and H form a horizontal loop 25L As shown in FIGS. 5 and 6, in accordance with the invention, decorative ribbons (501, 601) of different color, shape and fabric may be tied to and/or around the horizontal loops (also referred to as side straps) and to and around the foot of a wearer of the footwear. Note that as configured when the ribbons pull up on a loop (e.g., 25L) the corresponding opposite loop (e.g., 25R) is pulled in (i.e., tightened). In addition, depending on the configuration more than one loop can be tightened.

In FIGS. 3 and 3A, a second string/strip 302 (in addition to string/strip 301) shown beginning at the one end H of tunnel 47 is passed through tunnel 47 to the end of the tunnel at point G and then along the outer (heel) side of the footwear to form a “heel” loop 27 curving back to point H. The two ends of string 302 are attached to each other at point 321 located at or near an end of tunnel 47. Loop 27 is formed as a separate heel strap 27 because it was found to be useful in securing the footwear to the heel of the wearer and to decorate the back of the foot and ankle. The rear heel portion of loop 27 may include a further internal loop 272 as shown in FIG. 2G.

In FIG. 3A four (4) separate strings (301, 302, 303, 305) are wound around the tunnels 41, 43, 45, and 47, to form: (a) side straps 21L, 23L and 25L along the left hand side of the footwear; (b) side straps 21R, 23R and 25R along the right hand side of the footwear; and (c) heel strap 271. The two ends of each string are attached together (string 301 at 311, string 303 at 323, string 305 at 325, and string 302 at 321).

In FIG. 3B a single string 301 is wound around the tunnels for the full extent of the footwear to form all the side straps (21L, 23L, 25L, 21R, 23R, 25R) and the heel strap 27.

In FIG. 4 a single strip 301 is wound around all the tunnels and along all the sides and around the back of the heel with the two ends of the strip 411A and 411B exiting from tunnel 47 in opposite directions. The two ends (411A, 411B) can be pulled to tighten the loops. The two ends can also extend above the ankle of the wearer (user) to provide additional attachment. This demonstrates the versatility and modifiability of the structure. Note that the ends (411A, 411B) of the string/strip 301 can include a strip of Velcro (or any other suitable attaching means) to enable the two ends of string/strip 301 to be attached easily.

FIGS. 5 and 6 illustrate the foot of a user wearing footwear with ribbons (501, 601) embodying the invention. Ribbons (501, 601) may be of different color, shape and fabric. As shown, the ribbons can be wound around the loops or side straps to form many different configurations to modify and alter the appearance of the footwear, as desired by a wearer. In addition to selectively altering or modifying the appearance of the footwear, the ribbons by pulling on the loops function to tighten and secure the loops and also to tighten and secure the footwear to the foot of the wearer. Clearly, footwear is provided whose appearance can be easily and repeatedly modified by the wearer.

In accordance with the invention kits may be formed which include right and left shaped soles (with the strips pre-inserted) and an assortment of ribbons. The strips may also be of different colors and materials. Likewise, the ribbons may be of different colors, shapes and fabrics. The strips may be pre-inserted and wound around the tunnels and along the side or left to the user.
